The Lizzie McGuire Movie was arguably one of the most defining of our generation.
From Gordo and Ethan's unlikely kinship to Lizzie's stellar on-stage moment, we we're all empowered by the film's central message of friendship over love interests, despite how appealing they may seem.
Hilary Duff sat down with The Hollywood Reporter to discuss her thoughts on the movie, and divulge some of her favourite memories from it 15 years on.
Originally coming out in 2003, the film follows Lizzie and her school friends (and enemies) on a trip to Rome.

'It was really fun to be on the catwalk, and change clothes a bunch of times, and be in a bubble-wrap dress,' she told THR.

The Alice in Wonderland star made her film debut in The Princess Diaries in 2001. Three years later she reprised her role as Mia for the The Princess Diaries 2: Royal Engagement.

Legally Blonde was a movie that spoke to many of us, and now Reese Witherspoon is here to celebrate its 15th anniversary.
